Jt. Horstmann et al., CHARACTERIZATION OF SUB-100 NM-MOS-TRANSISTORS PROCESSED BY OPTICAL LITHOGRAPHY AND A SIDEWALL-ETCHBACK TECHNIQUE, Microelectronic engineering, 30(1-4), 1996, pp. 431-434
This paper describes the fabrication of NMOS-transistors with a geomet
ric gate length of down to 50 nm using conventional optical lithograph
y and a modified sidewall-etchback process. Based on measurements the
transistors are characterised and their device parameters are compared
to simulations. Finally the procedures for further optimisation of th
e process will be explained.
